Occipital lymph nodes

Occipital lymph nodes are a group of lymph nodes located in the occipital region of the head, which is at the back part of the skull. These nodes play a crucial role in the lymphatic system, which is part of the body's immune system.

Etymology

The term "occipital" comes from the Latin word "occiput" which means "back of the skull". The term "lymph node" comes from the Latin word "lympha" which means "water", and the Greek word "node" which means "knot".

Anatomy

The occipital lymph nodes are typically located at the base of the skull, near the occipital bone. They are usually grouped in a cluster of one to three nodes. These nodes receive lymphatic drainage from the posterior scalp and neck.

Function

The primary function of the occipital lymph nodes is to filter harmful substances from the lymph that is drained from the scalp and neck. This helps to prevent the spread of infection and disease.

Clinical significance

Swelling or enlargement of the occipital lymph nodes, known as lymphadenopathy, can be a sign of infection, immune disease, or cancer. This can be detected through physical examination or imaging studies.
